yading@10: 
yading@10: The libswresample library performs highly optimized audio resampling,
yading@10: rematrixing and sample format conversion operations.
yading@10: 
yading@10: Specifically, this library performs the following conversions:
yading@10: 
yading@10: @itemize
yading@10: @item
yading@10: @emph{Resampling}: is the process of changing the audio rate, for
yading@10: example from an high sample rate of 44100Hz to 8000Hz. Audio
yading@10: conversion from high to low sample rate is a lossy process. Several
yading@10: resampling options and algorithms are available.
yading@10: 
yading@10: @item
yading@10: @emph{Format conversion}: is the process of converting the type of
yading@10: samples, for example from 16-bit signed samples to unsigned 8-bit or
yading@10: float samples. It also handles packing conversion, when passing from
yading@10: packed layout (all samples belonging to distinct channels interleaved
yading@10: in the same buffer), to planar layout (all samples belonging to the
yading@10: same channel stored in a dedicated buffer or "plane").
yading@10: 
yading@10: @item
yading@10: @emph{Rematrixing}: is the process of changing the channel layout, for
yading@10: example from stereo to mono. When the input channels cannot be mapped
yading@10: to the output streams, the process is lossy, since it involves
yading@10: different gain factors and mixing.
yading@10: @end itemize
yading@10: 
yading@10: Various other audio conversions (e.g. stretching and padding) are
yading@10: enabled through dedicated options.
